I tried pushing the knob in, didn't work. What switch would you recommend me getting. I'm not super great at soldering, I have the solder sucker thing and a soldering iron, I don't think I have the proper solder though. Links? :) Thank you for your responses!

I need some help!   I bought a Bravo V2, finally came after nearly a month of waiting. I got it for my xbox, to plug my rca into, then Sennheiser HD555's for the goodness. I used it for a game of call of duty, then had to go do whatever. I was busy for 5 days so it was just sitting there...
